Application tiled November 4, 1901. Serial No. 81,040. (No model.)

To @ZZ whom it may concern;

Beit known that LLUCIEN GENTY, engineer, a citizen of the French Republic, residing at Marseilles, BoucheS-du-Rhne, France, (and having post-office address 6l Rue St. Jacques, in said city,) have invented certain new and useful Improvements in Gas-Producers, of which the following is a specification.

This invention relates to gas producers working by suction, and has for its object to provide a device for regulating the amount of steam required for the air and steam mixture supplied to the producer.

According to this invention a mixture of air and Steam is produced in any known way; but the mixture is regulated in such a manner that the amount of steam is not sufficient for the production of the gas in the genera-y tor. The necessary amount of steam is furnished by a complementary supply produced by a dierent apparatus from that which provides the steam for the irst mixture, the said complementary supply being regulated by a device as hereinafter set forth and which is regulated by means of a steam-regulating device operated bythe variations of temperature of the gases escaping from the gas-producer.

The principle of the regulating'device is as follows: The temperature of the gas evolved from the producer decreases when the steam is supplied in excess to the generator, and, on the contrary, the temperature of the gas'rises when the amount of the steam-supply is not sufficient. Therefore the invention aims to provide a regulating device adapted to increase or decrease the complementary amount of steam, according to the volume of the gas generated.

In order that the invention may be clearly understood, reference is had to the accom panying drawings, wherein like reference char. acters denote corresponding parts throughout the several views, and in which- Figures 1 and la when taken together form an elevation, partly insection, of a gas-producer provided with the improved regulating device accordingto this invention. Fig. 2 is a sectional elevation, on an enlarged scale, of the regulating device.

Referring to the drawings, the right-hand part of which shows a gas-producer providedV with a hearth a, a shaft b, a retort c, an ashpit d, a pipe e, leading from the top of the retort c to the lower part of the Shaft b, and

through the said pipe `@the most volatile products of distillation are returned to theshaft by means of an exhaustertl or other suitable device communicating with the pipe e. The gases escape from the producer through a pipe 7L, communicating With an annular space g, interposed between the retort c and the shaft b. The gases escaping from the producer through the pipe h enter the regeneratorj, surrounded by a jacket I, and heats the water con-l tained in the boiler Z and then passes through the pipe m to the scrubbers m', where they are extracted by an exhauster provided with a fan n. The air and steam mixture is adapt ed to enter the tubes 7c, extending within the regeneratorj. The air is drawn in the apparatus by the fan n of the exhauster and enters lthrough an inlettube t, opening into a chamber u, provided at the top of the gas-producer and above the boiler f, Surrounding the producer, the chamber u being in communication through an opening w with kthe steam-space of the boiler f. The opening w is arranged in the bottom Il of the chamber u ata point diametrically opposite to the air-inlet tube t. This arrangement compels the air entering through the air-inlet to come in contact with the Surface of the water in the annular boilerf, so that the air becomes charged with moisture and air and steam enter the regeneratorj through the tube The air and steam as they are fed to the regenerator j through the pipe oc are supplied through a pipe y, which communicates with the tube with a further quantity of steam from the boiler'Z, arranged in the regenerator j. The specific manner of the passage of the air and steam from the boiler f and when fed with additional Stoa In through the pipe y from the boiler l is that the air and steam first enter the chamber 10 at the top of the regeneratorj and then in the tubes 11, which open at their bottom into the tubes 7c, and after the mixture is heated in the tubes Za it passes out through the chamber 12 into the connectingpipe 0, which directs the mixture to the gas loo producer or generator. If it be necessary to add a further quantity of steam to the steam and air coming from the producer-boiler, it is, as before stated, supplied through the pipe y, and this additional supply of steam is regulated as follows: The boilers]C andZ are connected by a pipe c and the boiler Z is surmounted by a dome l, which is connected by a small pipe 2 with the regulating device and the tube y. Through the latter the steam passes from the boiler Z to the tube ai. A hand-wheel connected with a valve 3, controlling a passage at the top of the dome l, permits supply of additional steam to the air and steam coming from the boiler Z to be stopped; but the amount of this additional steam is regulated by a device constructed as follows: The outlet-pipe h, conducting the gases generated in the producer to the regenerator, is fitted with a cylindrical chamber 4, containing a central tube 5, closed at its lower end and iilled with air. The upper end of this central tube 5 is connected by a small pipe G to a vessel 7 containing mercury. A float 8 dips into the mercury and has a stem carrying a cylindrical valve 0, the apertures of which establish between the short tube 2 and the air-pipe y from the producer-boiler a com mnnication which varies with the position of the float.

The Working of this regulating device is as follows: If the temperature of the gas coming from the producer rises, it is because the combustion in the producer is too active. rlhe air in the central tube 3 expands and exerts pressure on the mercury in 7, and the float S and cylindrical valve 9, attached to it, rise, so that a greater amount of steam is taken from the boiler Z in the regenerator. If the temperature of the gases issuing from the producer decreases, it is because steam is supplied in excess, and the reverse action of the regulating device decreases the amount of steam supplied to the air. These changes in the amount of steam supplied allow to keep the hearth at a temperature as constant as possible, like a watchful Stoker, and this is the condition of a good working. When the amount of steam taken from the regeneratorboiler Z decreases, the pressure of thest-eam accumulating in this boiler forces back a part of the water in to the producer-boilerfthro ugh pipe connecting the two boilers, and therefore the regulation of the pressure is completed by the fact that the heating-surface in contact with the water of the regeneratorboilerZvaries with theamount of steam which this boiler has to generate. If this amount is below, the steam is superheated by the heating-surface of the boiler which is not in contact with the water.

As indicated by the arrow in Fig. I, the gas passes from the producer through the pipe h into the regenerator and then out of the regenerator through the pipe m into the scrubber, where it is exhausted by means of the cxhaustcr. The passage of the gas through the regenerator and out therefrom is indicated by arrows in Fig. 1. The air enters at t, as indicated by the arrow, and passes into the producer-boiler, and from there the air and steam pass through the pipe 0c into the chamber lO, as indicated by the arrow, and into the tubes Zt, and then pass up the tubes Zr, as indicated by the arrow, into the pipe o, as indicated by the arrow, and then into the producer, as indicated by the arrow. The steam from the regenerator-boiler passes therefrom through the regulating means into the pipe fy, as indicated by the arrow, and then into the pipe a2. The operation of the regulating device for regulating the amount of steam required for the air and steam mixture as the latter passes from the producerboiler through the pipe has been hei-einbefore referred to.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
